Powers:Like all Ul'lula'ns, Nebulon's true form was that of a 10-foot tall, semi-amoeboid/octopoid creature with six tentacles. Nebulon possesses a vast amount of super-human strength. He possesses a number of super-humanoid powers which draw upon the biospheric energy of planets. He can manipulate energy for a variety of effects, including the creation of spheres, shields, or energy bolts, capable of staggering the Hulk. He can teleport across the surface of a planet and between dimensions. His powers wane when he is no longer in proximity to a planet, thus he can not teleport across space. He can also shape-change, more than other U'la'lans could, though it leaves him very drained.

Bio:Ul'lula'n, would-be-world conqueror, originally came to Earth to steal mineral resources for his world, founded celestial mind control movement, formerly utilized Squadron Sinister + Lubderbites + Porcupine + Eel + Plant-Man as agents, former mate of Supernalia, seemingly convinced by her to commit suicide via exposure to energy draining ennui-ray to regain honor, actually used an illusion to fake his death to get rid of her.
